This Week in Nature

In Nature Biotechnology this week, Massachusetts General Hospital researchers report on a technique for obtaining greater nuclease specificity with the gene-editing tool CRISPR. CRISPR works when Cas9 nucleases, directed by guide RNAs, cause double-strand breaks in specific DNA sequences. However, these nucleases can cause mutations at sites that differ by as many as five nucleotides from their intended targets.
